Answer:
Step-by-step explanation:
hey there!!!
we know already that the area of a triangle is given as
where b= base
and h= heigth
Given that the height is 5 times more than twice it base
let h= 2b+5
Now we substitute h=2b+5 in the area of the triangle
X = 47 + 9y
xy = 1860
y(47 + 9y) = 1860
47y + 9y² = 1860
9y² + 47y - 1860 = 0
> using a quadratic equation solver on a calculator but you can also use the quadratic equation = [-b+/- √(b²-4ac)]/(2a)
> only integer solution is x = 12
12y = 1860
y = 155
integers are 12 and 155
Answer:
Assuming "the speaker takes up 1/6 of the internal volume"
volume is 9³ in³
you want the remaining volume, which is 5/6 of the total
(5/6)9³ = 607.5 in³
double that if you want the remaining volume for BOTH speakers....
Answer:
Hi there!
6/15 is the probability that the marble is black!
Step-by-step explanation:
Oki, so lets's find the total number of marbles first!
8 + 6 + 1 = 14 + 1 = 15
And just turn it into a fraction!(very simple and easy)
6/15
